Check these 3 parameters before buying battery Inverter/UPS

Undoubtedly, the Charging Section is the most important area of the battery inverter/UPS as it defines the Charging time.https://en.wikipedia.org/wiki/Power_inverter

To understand the charging time, one has to understand the charger’s capacity, which has been designed by us so that it charges in the defined period.

Multiple types of batteries are available in the market, with advantages and disadvantages; accordingly, we charge them based on their characteristics.

For example, if we have to charge a Tubular Lead Acid battery, we have to take a minimum of 10 hours before completely charging it.

If we try to charge faster, these Batteries will be short-lived and need frequent water topping.

 

If we have to charge the Valve Regulated Lead Acid Batteries, which are called sealed Maintenace Free batteries, they need to be charged in 6 to 8 hours, and if we try to charge them faster than that, their life is also reduced.

In the case of Lithium batteries, we can charge them in 2 to 4 hours, and they are designed like that and have a double or 5-time life compared to Lead Acid batteries.

It’s very important how the charger of a UPS is designed to take care of the battery as the life of the battery will majorly dependent on the charger technology.

Our UPS has a charging capacity of 15 Amp, which can charge the 150 Ah battery in 10 hours and the 200 Ah battery in approximately 13 hours. So the charger size is very important to check before buying any UPS/Inverter.

The next parameter is how the charging is done. Is it flat charging, or it’s done in stages?

 

In Lead Acid, battery charging has to be fast till 80 per cent of the charge, but the rest, 20 per cent, needs little slow charging because the water is hot inside the battery when we are charging it, so we need to follow a pattern by which we reduce the heating when we are charging it so that water doesn’t evaporate and the more we control the heating the life of the battery is increased.

How the temperature affects the battery is very important to understand. External temperature is very important to take into consideration when we are charging the battery. If the temperature is high outside, charging is less to charge the battery, so the cut-off voltage is lower. Still, when the temperature is higher than the charging takes more time as we need to put in more charge to charge the battery. This technology completely is called ATC Automatic Temperature Compensation technology which is required by each type of battery to make it healthy and increase its life. Lithium’s temperature plays a major role, so we must stop charging if it crosses the desired temperature.

At Su-vastika, we have designed a six-stage charger to operate the charging based on the internal and external temperature of the battery.

The charging time and the inverter’s efficiency will define your home’s electricity bill.

People complain that their electricity bill has increased once the inverter/UPS is installed at home.

This is true because when customers choose UPS, they are not given enough knowledge about the product.

So we at Su-vastika designed the charger and Inverter technology based on an efficient charging circuit to minimize the bill. So it’s important to check the efficiency of the Charger and Inverter so that the battery size can be reduced if the inverter efficiency is higher.

The concept of trickle charging is also very important to understand as this can increase the electricity bill and reduce the battery life if not designed properly by the UPS.

 

The companies give the battery Life as a warranty by the battery companies.

So let us understand the concept of battery life as it depends on the UPS technology to maintain and increase the battery life or reduce it via charging.

Low Voltage areas.

In some areas, the voltage is very low, and charging doesn’t happen most of the time,t especially in rural areas, because the charger works under the range of specific voltage only like most of the UPS charger works properly from 140 to 270Volts. We at Su-Vastika designed our charger to work properly even if the voltage goes as low as 100 Volts. This helps properly charge the battery in 10 hours in the case of Lead Acid batteries.

The Inverter part of the UPS system works when the main power goes, converting Electricity from DC to AC from the battery.https://www.kunwersachdev.com/thoughts/personal/all-in-one-technology-coming-inverter-ups-and-off-grid-ups-is-going-to-be-the-future/16/

In this scenario, the power quality becomes very important for the UPS. So there are three major portions.

1. Waveform of the Inverter
2. The voltage and frequency
3. Switching Time

So let us start with the Waveform. When the Mains line goes in the house, and the Inverter kicks in, then people hear the noise in the fans, and people come to know that fans are working on Inverter or UPS as the noise created in the fans is because of the impurity in the waveform. So companies use various types of terminologies like sinusoidal. 

 

A square wave or quasi sine wave etc., but all these waveforms create noise and heat in the appliances and reduces the life of the appliances. The waveform we get from the Electricity department is pure Sinewave, so why do we take a UPS which doesn’t give us Pure Sinewave? We at Su-vastika design our products based on Pure Sine wave only so that you can run any sensitive appliances on our UPS, like TV, Computer Music Systems, etc., with peace of mind.

The voltage required for running the appliances is generally good for appliances is 200 to 230 volts which is ensured by our UPS and the Frequency of 50 Hz only.

The switching time in UPS is crucial so that TV and appliances are not interrupted when you watch any serial or work on the computer, where the data will be lost. So we at Su-vastika designed our switching time, which is less than five milliseconds, so that no appliances can see the power cut happening and they work uninterrupted.
